PHILIP BECKMAN, OF NAPIERVILLE, ILLINOIS.

LEATHER-ROUNDING MACHINE,

Specification forming part of Letters Patent No. 39,335, dated July281863.'

`To all whom it may concern:

`ters in the several figures indicating the same parts, and in whichdrawings- Figure I. represents a perspective view of my improvedmachine, a section or strip of leather being shown in red lines as inthe act ofbeing rounded Fig. 2 is a vertical section taken through thecenter of one of the rounding holes'or apertures through which theleather is passed in using the machine. Fig. 3 is a perspective viewofthe machine or implement thrown open.

As heretofore constructed, implements for rounding leather, in use byleather workers, have been composed of parallel bars of metal, hinged atone end, with rounding-holes so applied that one-half of each holeshould be. in the two bars, but with the adjoining working face of thebars between the holes on an nninterrupted horizontal plane. -In otherwords, under the old plan of construction the worin ing or adjoining'faces of the bars were made with a single plane' 'surface ordividingjoint throughout the working length ot' theimple ment, asindicated by the line a' 00,'Fig. 2. By

this Inode of construction,V however, the

leather, while being passed through the implement, was subjected toacreasin g orscratching of itssurface by being forced into the jointbetween the bars, thereby greatly detracting from the workmanlikeappearance of the rounded leather. By my invention 1 this objection isobviated.

In the drawings, A A are metallic bars perd, adapted to tit in ears orlugs e, projecting.

upward from the lower bar, A', and be secured therein by a pin,f, passedthrough perforations g g1 in the handle Land lugs@ as clearly indicatedby Figs. 1 and 2. The adjoining face of the b'ars A'A, instead of beingmade.

with a single plane surface or dividing-joint throughout the -workinglength of the implenient, is made with lapping projections h and Ih', soas to break joints when the impiement is closed, as shown in Figs. l and2.

The projections h on the bar A arid h on the bar A are situated uponopposite sides ofthe respective bars, and thus overlap each other whenthe'implement is closed, as clearly shown in Fig. 2. It will thusbe seenthat when leather is being rounded, as indicated in Fig. 1, there is nodanger of having the surface of the leather pressed into thedividing-joint of the bars so long as the projections h and h are madeto overlap while the leather is in the act of being passed through theroundingholes of the implement.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

As a new article ot' manufacture@ leatherworker-s rounding-machine soconstructed that the adjoining faces of the parts between which theleather is rounded shall overlap, in the manner and for the purposesubstantially as set forth. i
